To all 'wheat/it may concern l Be it known that I, )ect of the Emperor of Germany, residing at Obcrndorf-on-the-Neckar, Wurttemberg, in the Empire of Germany, have invented a certain new and useful Improvement in Automa-tic Firearms, of .which the following is a specification. b

The invention relates to firearms with detacha-ble magazine and means for locking the breech block in the open position on the removal of the emptied magazine. Y

The invention hasfor its object to provide means for locking also the firing mechanism o when the magazine is removed.

An embodiment of the 'invention is illustrated by way of example in theaccompanying drawing, in which Figure 1 is a general View of the firearm (closed) lwith magazine insorted, av portion of the Ibreech block being broken away and the side plate covering the trigger mechanism removed. Fig. 2 is a lon- .-gitudinal section with the parts inthe same z position as in Fig. 1. Fig. 3 shows the posifion of the parts with the magazine removed. Fig. 4:' is avertical cross section of Fig. 3. Figs. 5 and ,6 show the locking member in front elevation and in top view. Fig. 7 is an elevation of the breech block partly in sec- The locking member 7c, which is pivotally vmounted at g1 in the frame g of the firearm, presents the form of a two-armed lever the which engagesthe breech block h when the magazine is removed while the front arm k2 passing through a recess in the rear Wall m1 of the magazine fm, acts as ejector when the magazine is inserted in the o frame.

The locking member k is acted upon by a spring f which is held in the frame by two clamps g2 formed on the frame g and embracing the 5 length on both sides (Fig. 1). This spring f serves also to hold the magazine m in the frame. For this purp a nose f1 atits lower portion engaging a notch in the rear wall m1 of themagazine o (Fia 1)- In accordance with the invention the lock- .ing member is so shaped that it isable to lock also "the firing mechanism when the magazinejis removed. In the embodiment 5 5 of the invention illustrated in the drawing Specication of Letters Patent. Application filed August 30, 1913. Serial No. 787,515.

member with alateral projection c which 1n the locking position engages beneath a shoulder al Von the rear arm of the sear'a', preventing the downward movement of the latter which is necessary for the release of this yis effected by providing the locking thereby the striking bolt, so that, when the magazine is removed, the striking bolt cannot be released.

When the magazine m is inserted, the lever lo is held bythe rear Wall m1 of the magazine acting on the projection 7c3 of the lever 7c against the pressure of the spring f in the position in which it acts with its front arm (Figs. 1 and 2). )hen the last shot from the magazine is fired, the breech block L' is locked after the 4recoil in the rearward- (open) position in the known manner, forinstance by the mags azine follower. Now the empty magazine is removed to be exchanged for a full o ne. Of

course the magazine follower is also removed *i f so that the breech block would be released and return into the forward (closed) p osition. But now the lever k which is no more locked by the magazine wall m1 in the ejector position (Fig. 1) is rocked by the spring f acting on the stud if* so that the rear arm k1 of the lever enters the recess h1 in the breech block h thereby locking the same in the open position (Fig. 2). At the'same time the -lug c of the locking ley/er 7c engages beneath the sear` a thereby locking also the firing mechanism. When a maga- `zine is again inserted in the'firearm its rear wall m1 presses the projection 7c3 of the lever k upward, so that this leveris again rocked into the ejector position (Fig. 1) against the. action of the spring is thereby released from engagement with. the rear arm k1 of the lever cso that it can freely Imove into the closed position. In thisv cesses h1, h2, one or'other of which is engaged by the rear arm k1 of the locking the open or in the closed position. The sec# -ond recess 71.2 enables the locking member to lock the firing mechanism also when the breech block is in the closed position.

f. The breech block hf member according as the breech block is in gangement with IVhat I claim and desire to secure by Letters Patent of the United States is In a firearm, the combination of a breech block, a firing mechanism, a detachable magazine, and means adapted to lock the breech block in the open position and also the firing mechanism when the magazine is removed.

2. In a firearm, the combination of a breech block, a firing mechanism, a detachable magazine, and means adapted to act as an ejector when the magazine is in the frame and also adapted to lock the breech block in the open position and also the firing mechanism When the magazine is removed.

3. In a firearm, the combination of a breech block, a firing mechanism, a detachable magazine, a pivotedtwo-armed lever, one arm of said lever being adapted to act as an ejector when the magazine is in the frame, and the other arm being adapted to lock the breech block in the openv position when the magazine is removed, and a lug on lsaid lever adapted to lock the firing mechanism when the magazine is removed.

4. Ina firearm, the combination of a breech block, a firing mechanism, a detachable magazine, and a member adapted to lock the breech and also the firing mechanism When the magazine is removed, and means for bring- .ing said locking member into locking engagement with said` breech block and with said firing mechanism.

5. In a firearm, the combination of a breech block, a firing mechanism, a detachable magazine, and a member adapted to lock the breech block in the openl position and also the firing mechanism when the magazine is removed, and means for bringing said locking member into locking engagement with said breech blockand with said firingmechanism, said mears being adapted to be counteracted by said'y magazine to hold said locking memberout of locking engagement with said breech block and with said firing mechanism.

6. In a firearm, the combination of a breech block, a firing mechanism, a detachable magazine, and a member adapted to lock the breech block in the open position and also the firing mechanism when the magazine is removed, and means for bringing said locking member into locking ensaid breech block and with said firing mechanism, to press said lockingA member into locking engagement with saidbreech block and With said firingmechanism.

7. In a firearm, the combination of a C'bpiel oi' this patent may be obtained for ve cents each, by addressing the block in the open position"I and a spring adapted,

ing said locking member into locking engagement with said breech said firing mechanism, and a spring for holding said magazine in the frame and adapted to press said locking member into -block and with' locking engagement With said breech block and with said firing mechanism.

8.
